Holder (Joel Kinnaman) and Linden (Mireille Enos) confront Rosie's teacher, Bennet Ahmed (Brandon Jay McLaren), about his relationship with the deceased girl and his whereabout on the night of her murder. He admits to exchanging notes with Rosie but denies any involvement in her death. Instead, he lauds Rosie's creativity and intelligence and hands over a Super 8 film, which he insists they watch.

Linden has prints made from the film, while Holder looks into Ahmed's story about working on some flooring in his home the night of Rosie's murder. Linden and Holder pay a visit to Ahmed's home while he is out and talk with his wife, who is also a former student. Holder tries to knock down Ahmed's alibi while Linden checks out the nursery he was working on, where she finds a bottle of ammonia. Linden later learns that ammonia was used in Rosie Larsen's murder, possibly to hide evidence of sexual assault.

Mayoral candidate, Darren Richmond (Billy Campbell), meets Jamie (Eric Ladin), his former campaign manager in the early morning hours. They discuss Jamie's meeting with Mayor Adams later that day. After meeting with Adams and getting drunk, Jamie learns that it's Councilwoman Utenis, not Adams, who's leaking information from inside the campaign. Jamie suggests Richmond's campaign adviser and girlfriend, Gwen, is the one supplying information to Utenis but it's later revealed that a male aid is the source of the leak.

The Larsens continue to struggle with the tragic loss of their daughter, Rosie. Stan (Brent Sexton) faces some unexpected expenses in attempting to sell the new home he bought for the family. Meanwhile, his partner, Belko (Brendan Sexton III) offers to get some inside information on who the police are investigating at Rosie's school. At first, Stan declines but after a visit to the funeral home, he's overcome with grief, and asks his partner to find out what is going on at the school.

Breakdown:

If there's one thing we can walk away from "The Killing" with, thus far, it's that it's never sunny in Seattle. The relentless rain and oppressive dreariness of the city, as portrayed here, serve to make sure we don't forget this a show about death, grief and the dogged pursuit of justice in the face of a potentially vast conspiracy. Not even half way through the first season and the series is visually unmistakable. But can you blame Linden for wanting to move to Sonoma?

With a suspect in their sights and evidence piling up, Bennet Ahmed is looking good for the murder of Rosie Larsen. But a neatly wrapped up case at this point just screams red herring. Ahmed is most likely not the man at the center of the "whodunit?" but if "The Killing" plays out as intelligently as it promises to, his thread in the plot is more than coincidental.

Ahmed's connection to the Richmond campaign is intriguing and hopefully, serves to tie the two divergent storylines together, soon. Up until now, the matter of the Richmond campaign's internal crisis has made for a decent B-storyline, but how it relates to Rosie's murder investigation, is unclear.

In this hour, the two storylines connected in an intense scene between Richmond and Rosie's mother, at a grocery store. As the Larsens grow increasingly frustrated with the police investigation and Richmond struggles to handle the negative effect his association with the murder has on his campaign, hopefully the two begin to crossover in a meaningful way.

As the family at the heart of the tragedy, Michelle Forbes and Brent Sexton continue to put in incredible performances as the grieving parents of Rosie Larsen. It's a testament to how excellent both the writing and the acting in "The Killing" is, that it can straddle the line between a methodical police procedural and a moving emotional drama, so fluidly.
